A comparison of the two-way binding in AngularJS, EmberJS and KnockoutJS
summary
AngularJS uses dirty checking on a scope requiring explicit apply cycles and the demo shows it slows as the model grows; EmberJS and KnockoutJS use observable properties, but Ember batches rendering and becomes noticeably slower rendering a 5,000‑item list while Knockout updates the DOM synchronously and can crash when pushing 5,000 items one by one. Computed examples convert Celsius to Fahrenheit: Angular recomputes too often, Ember needs static declared deps, and Knockout demonstrates dynamic dependencies that track only used values.
